Yeah its about some upper/lower case letter something like this - TodayIsTuesday2019 so I'm missing upper case letter or variation - IsItTuesdayToday2019...
Which app you are recommending for brute force? And is it possible to brute force second password on MultiBit/Blockchain.info with that app?
Thanks.
In this case,
btcrecover should find the correct passphrase in a very short amount of time.
For x letter in your password, it needs to check 2
x variations.
With 10 letter, there are 1024 possibilities (which is a really low number for bruteforcing). This would probably run through in less than 5 seconds.
btcrecover is extremly slow for wider searches, You need to have custom made version that runs on GPU, then you can reach over 500k guesses per second.
